Package: courier-mta Severity: normal Hi,
it looks courier do not unlink files it create but write failed. This happens for example when user have filled its filesystem quota, but still not reached inode limit. Thus user can create files and directories, but cannot generally use more space in files itself. (I'm using ext3 over nfs4). It would be useful if courier will detect that: - file in tmp was created successfully, - first write returned error, of any kind. Then in such condition close file, ignore error (on write or close), unlink temporary file, and return error to the connected smtp client Eventually errors be interpreted to return appropriate error message to the sending side (i.e. mapping EIO or ENOSPC to generic messages, to not leak any details which could be in errno message), and to loging purpose (based on errno message). Some errors of course can be because courier does something very wrong (i.e. passing read-only file descriptor to write), but I assume normally all this will not happen. Most normal error will be due to the transient problem (i.e. EINTR), or because of system limits (like EMFILE, and even in such situation it is more probably that open/create will fail than write). Impossible errors (like EPERM on write) should also be handled the same way, but of course it is probably an OS fault here. So in all cases it will be safer to perform this rollback (there was nothing yet written to file, what can go wrong?). And handle few cases (ENOSPC would sufficie) to given proper message (like "No free space available"), and rest mapping to generic error (like "IO Error") Thanks. -- System Information: Debian Release: 6.0 APT prefers stable APT policy: (500, 'stable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/1 CPU core) Locale: LANG=pl_PL.utf8, LC_CTYPE=pl_PL.utf8 (charmap=UTF-8) (ignored: LC_ALL set to pl_PL.utf8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
